'To all 'whom t may concern:

Be it known .that I, Enna J. HUBBARD, a

citizen of theUnited States, and a resident fof Berwyn, in the county ofCook and State of Illinois, havefinvented certain new and useful'Improvements in Spools, of which the following is a specification.

My invention relates to spools or 'reels constructed of sheet metal andadapted particularly for holding material such as wire.

The object of my invention is to provide construction. and arrangementwhich willy enable the various parts toe accurately in-y ter-connectedand secured gether to form a strong rigid anddurablestructure.

On the accompanying drawing, I show a invention are incorporated. Onthis drawing?- l? ig. 1 is a side elevational View,

Fig. 2 1s an end view with.f parts broken away, and

Fig. 3 is a sectional View on plane ange ends 6 and.7 b means of,tongues 13 which extend throng the slots 14 in the tlange ends and arebent outward radially to lie against the outside of the ange ends.

The plates 9 and 10 are concentric with the 'f fiange ends and neartheir edges the. plates overlie the tongues 13, the lates, tongues andilange ends being rigi y secured together by spot welding.

The spindle tube 8 is also preferably formed by rolling up a piece ofsheet metal to cylindrical form. The flange ends and 7 have the axialopenings 15 whose diameter is such as to receive the ends of the spindletube. The plates 9 and 10 have the axial openings 16 whose Adiameter issubstantially equal to the inner diameter ofthe spindle tube, thespindle tube at its ends thus extending through the openings in theliange ends and abutting against the plates 9 and 10 adjacent theiropenings 16. L Adjacent theirouter edges tlie plates 9 and 10 aredeilected inwardly to engage against the ilange ends 6 and 7, and attheir inner edges the plates are depressed as indicated at 17 in orderto engage with and seat against the flange ends. At its ends the spindletube has the tongues 18, and to receive these tongues the plates 9 and10 at`their openings 16 are provided with slots 19 whose depth isiequalto the thickness of the tongues. After the parts are assembled thesetongues are de? iiected outwardly and radially to abut aga-inst theplates 9 and 1 0 in the depressed section 17 thereof. As the flangeends, hub,

and the plates are securely welded together,

and the spindle .tube tongues` are anchored inthe slots of the platesand abut against the outside of the lates, the spindle tube is securelyand rigid y anchored in place, and i such rigid anchorage of the spindletube assists materially in 'holding the spool end wall struc-tures inplace and strengthening them. At the same time the bore of the' spindletube isentirely smooth so that the spool can readily turn on aLsupportingv spindle or other holder.

Thespoolend wall structures arefurther strengthened by curling theperipheral section of'the flange'ends 6 and 7 outwardly and 'downwardlyas indicated at 20. The thickness of this curled edge is such that theouter faces of the plates 9 'and 10 will be coincident with or withintheA outer surface 0f the curled edges, and the tongues 18 ofthe spindletube are within. the outer faces of the plates so thatthe spool can seatflatly and securely on its ends or on spindle slipports. The plates 9and 10 present smooth outer surfaces which offer very little resistanceto turning of the spools during uni winding thereo I thus produce a simle,'strong, durable and eiiicient spool capa le of withstanding the Wearand tear to which it will be subjected. The spindle tube cannot workloose because of its'secure anchorage both against lon itudinal androtational displacement.'

avng as follows: v

1. ,In a sheet metal spool, the combination described my invention, Iclaim .of a cylindrical core, flange l ends having openings, the ends ofsaid coreJ extending through said openings and' being turnedover-against the outer faces of said ilange ends,` pla-tes appliedagainst the outer sides of said` Hangs ends, said core ends bein weldedto said flange ends and plates, sai

flange ends and plates having axial ppenl said plat/es whereby ings,anda spindle tube extending axially through said core and through saidopenings and having its ends turned over against the outer faces of saidplates.

2. ln a sheet metal spool, the combination of a cylindrical core, flangeends secured to said core, plates concentric with said dange ends andsecured against the outer faces thereof, said plates having axialopenings,I

l@ a spindle tube extending through said core,

tongues at the ends of lsaid tube, said plates having notches at theiropenings, said tongues extending through said notches and beingdeflected against the outer faces of said tube Will be anchored againstlongitudinal and rotational displacement.

i 3. ln a sheet metal spool, the combination Y@of a hub having tonguesat its ends, flange ends having openings for receiving said tongues,said tongues being 'deflected radially t`o engage against the outerfaces of said ends, plates'concentric with said ends and overlying saidtongues, said tongues being welded tosaid ends andv plates, said plateshaving axial openings and having'passage- Ways adjacent said openings, aspindle tube v extending through said hub, and tongues at the ends ofsaid spindle tube extending through said passagevvays and deflectedradially against the kouter faces of said plates, whereby said tube willbe anchored against longitudinal and rotational displacement.

f 4. ln'a sheet metalspool, the combinationl of a cylindrical hub,flange ends for said hub, plates concentric with said ends and appliedagainst lthe outer faces thereof, said plates, hub and ends being weldedtogether, said plates having axial openings and havling notchesextending radially from said openings, `a spindle tube extending throughsaid hub and abutting at its ends against said plates, and tongues atthe ends of said tube extendingr through said notches and deet tlectedradially against theouter faces of 'l said plates. v

intenso 5. ln a sheet metal spool, the combination of a cylindrical hub,ange ends secured to the ends of said hub, plates concentric With saidends and secured against the outer faces thereof, said. plates havingaxial openings and notches extending radially from said openings, aspindle tube extending through said hub, and tongues at the ends of saidspindle tube extending through said notches and being deflected againstthe outer faces of said plates, said lplates having annular depressionsaround their openings for receiving said tongues and whereby saidtongues will be Within the planes'of the outer/faces ofsaidplates.

6. ln a sheet metal'spool, the combination ofv a cylindrical hub, flangeends secured to said hub, plates concentriclvvith said flange ends andsecured against the outer faces thereof, a spindle tube extendingthrough said hub, said flange ends having axial openingsfsaid spindletube extending through said openings and abutting against said plates,said plates having openings register; ing with the bore of said. tube,said plates having notches extending from their openings, and tongues atthe ends of said tube extending through said notches and dei-lect- `edradially to abut against the outer faces of said plates, said platesbeing depressedto bring said tongues within the planes of the outerfaces of said plates.
